Chara-Ani limited/exclusive boxset
It seems that the first PS Vita game to have Nendoroid Petit will be Legend of Heroes: Trails of Zero Evolution (a.k.a Eiyuu Densetsu: Zero no Kiseki Evolution).
Yep, the game will have a limited/exclusive boxset, courtesy of Chara-Ani, that will include Nendoroid Petit Arianrhod among other exclusive stuff.
You can see some official photos of the Petit after the break. ^^
